This will be the fourth time I have had to replace the load control arms seals in as many years. What could be the reason for them leaking so often? I feel sure that I"m installing them correctley.

Replace the shaft as well and make sure you get shims in the cradle so it won't have any side play. If the shaft has any wear the new seals will leak. You don't want any play in the cradle either.

Get new style bushings and seals from Boling Manufacturing along with the shims.

I agree with he other 2 posters. Bolings seals instead of the JD seals along with a L/D shaft with no visible wear and remove all slack between drawbar support & trans.housing.

I also use Deere seals "and" the Boling seals this gives a Double seal,and the excessive end play is what eats the seal in the first place...

Are the boling seals better then the bushing with
seals in that you can still use the original seal
with also that deere sells?

If JD seals a bushing with a seal I think it's a Boling.

Thanks for all of the response, how do you eliminate the endplay? Are you talking about side-to-side?

Had the same thing on my 4010, never enough time to do it right so would slap a new set of seals in it. The root cause was the tapered bushing were worn, allowing "over movement" on the seals, crushing the seal's rubber. The tapered bushing are in the transmission case, and the "A frame" (the piece that the bottom 3 point arms attach to).

The tapered bushings allow the load control shaft to bend as the draft load increases on the two lower 3 point arms. The amount of bend is then transfered up through linkage to operate the 3 point valve to raise the arms during increasing load or to lower during decreasing load.

Replace the bushings, replace the load shaft (if bad/rusty/pitted), replace the seals, and shim out the side to side movement of the A frame. You should be good to go......

Yes side to side,, Deere offers large OD shims in a few different thicknesses,add what it takes between the A frame and the transmission case, you can see the end play if you grab the 3pt arms and work them side to side against the sway blocks, as the hitch sways through out the day it continues to work on the seals till they fail.It helps to remove the lift arms for times when they aren"t needed , we usually take ours off the smaller tractors in the summer..when we are making hay or clipping pasture.

How difficult is it to remove the bushings from the housing? Any tips would be appreciated.

I do know the new ones I got from JD had had a seal
or o ring in the middle of the bushing . I didnt
take them apart to see if it was just an o ring or
not but They did come in a sealed john deere
plastic bag .

It appears you're correct. Here's the numbers for the bushing & o-ring for a pre '69 4020 BUT I couldn't find the same type bush/o-ring for a 3010 from JD.
R221297 BUSHING ADD 18.75 USD 18.75 USD
A3606R O-RING ADD 2.70 USD 2.70 USD
